"Derrik removed a fair amount of sand box sand that i was having a hard time disposing of, then dug out 5 cement footing to our old playground and finally leveled and landscaped a section of our back yard. I couldn't be more pleased with his work. He even discounted his original estimate because we did not need top soil and I and my neighbor assisted ( if you want to call it that) some of the raking. I highly recommend Derrick and Northen Edge phil and beth"

Excavating questions, answered by experts

Yes. A metal detector is one of the quickest and easiest ways to find your septic tank. However, metal detectors can be too expensive (costing upward of $300 in some cases), and not everyone has a metal detector just lying around. If that’s the case for you, you can also take a long metal rod and poke it into the ground at regular intervals until you hit something—likely your septic tank lid.

There is no standard depth, but typically, septic tanks are buried between 4 inches and 4 feet underneath the earth’s surface. There are a few factors that will determine your tank’s depth, including the height of your bedrock, the distance between your home and the tank, and the depth of your main sewer line.

The best type of soil to build on is a mixture of sand and clay, known as loam soil. Loam soil has the best combination of these soil types to build a foundation on. The clay particles help with water retention, so it won’t erode like sandy soil might, and the sandy particles help with drainage, so you won’t see unsafe soil expansion or have an increased risk of leaks from water sitting against your foundation.

A crawl space can be as little as 42 inches below the grade of your house, but this is not always recommended in flood-prone areas. At a minimum, there must be at least 16 inches of clearance between the ground and the floor joists to access the space in an emergency.

The average cost for pool excavation is $2,500. This cost can range from $450 to $4,500, depending on the pool shape and size, time of year, and any need to move buried utilities. 

When excavating for your pool, you might have to move existing utilities. You can expect to pay an additional $15 to $25 per linear foot to move gas lines. To move a septic system, it’ll cost an additional $2,000 to $20,000. A pool that is 10 feet by 12 feet averages $450 to excavate, and a 20-foot-by-40-foot pool averages $3,020.
